The Dilo is a baked earthen jar; there is a special variety known as Ghaghar, which is larger than the average Dilo with a shorter mouth of the jar and more protuberance in the sides. Both are often used in Sindh. The clay for these instruments must be specially prepared by an expert potter to produce a consistent thin wall. The Dilo and Ghaghar are percussion instruments. Sound can be produced both by striking the sides of the jar, and manipulating the mouth. Traditionally, Dilo or Ghaghar are played as accompaniment for the Yaktaro (images and information from Baloch 1988).
